Due to the formal division of the Soviet Union on December 21, 1991, this aircraft was assigned to the Russian AF, coded 69 red. Russia sold it to Ukraine, when the latter struck it off charge it was sold to the USA and registered as N757SF on July 23, 2003. Later it was listed as Racer number "25". In the 2006 Races - Jet Class Gold - it finished seventh at 414.703 mph (667.400 kmh)."
